Canyons, the final frontier of the Pacific Northwest! Five lectures and two field sessions will teach canyoneering specific anchor and rappel techniques to sustainably explore hidden canyons and wild waterfalls.

Canyoneering (or “Canyoning”) is the sport of exploring canyons using a variety of techniques such as scrambling, climbing, rappelling, wading and swimming.  The term is most often used to describe technical descents requiring ropes, harnesses, and other specialized gear. This class will focus primarily on local aquatic canyons in the Pacific Northwest.

Course Information & Format

The Mazamas Canyoneering class takes place over approximately six weeks from late May through June. The class includes five lectures held at the Mazamas Mountaineering Center (MMC), two field sessions, and an optional July camping weekend outing following the class.

The application for the class typically opens in April.

No previous canyoneering experience required; however, participants should be familiar with belaying, rope management, wilderness navigation, and also be a competent swimmer. This is NOT a beginner class for rappelling. Participants must be able to safely execute a basic rappel without supervision. One way participants can achieve the required rappelling experience is by taking the Mazamas BCEP class.

Canyoneering History

Today, canyoneering is practiced all over the world, although it is most well known in Europe and the United States. In North America, its most commonly associated with the famous slot canyons of the Colorado Plateau, although it’s also practiced in the Rocky Mountains, the Sierra Nevada, Arizona, British Columbia, Mexico, Hawaii, and here in the Cascade Range. With one of the greatest concentrations of waterfalls in the world, canyoneering is a natural fit for the Pacific Northwest.

Like climbs, canyons can vary widely in level of difficulty:  ranging from the easy hike-through variety to the extremely technical. Dry canyons are significantly easier in terms of rigging and preparation compared to those with flowing water.  The more water that’s present, the more difficult the canyon becomes.

While there are many similarities between canyoneering and climbing, the two are unique sports with unique techniques and hazards.  Experienced climbers may find their skills do not translate entirely to the canyon world; there’s a lot more to learn.
